Facebook has been flooded with disinformation ahead of the EU elections despite efforts by the social network to stop fake news from going viral, a study by nonprofit advocacy group Avaaz found.

During the last three months, Avaaz researchers found 550 pages and groups along with 328 profiles that appeared to be spreading disinformation in Germany, the UK, France, Italy, Poland and Spain. Avaaz, which reported the accounts to Facebook, said the social network pulled down 77 pages and groups as well as 230 profiles.

By then, the damage was already done. Disinformation posted by groups, pages and accounts that Facebook removed were viewed an estimated 533 million times over three months, according to the study.
